OIL-BURNER.

T 0 all whom it may concern:

Be it known that I, TALTER SUTTON, a citizen of the United States,residing at Sacramento, in the county of Sacramento and State ofCalifornia, have invented certain new and useful Improvements in Oil-Burners, of which the following is a specification.

My invention relates to that class of oilburners in which the liquidhydro-carbon is subjected to the vaporizing action of air or steam orboth, and the mixture thus formed ignited at a suitable tip.

The objects of my invention are, first, to provide for a thorough mixingof the oil with the air or steam before being discharged from the burnertip; second, to effect this mixing in such a manner as to promote thepassage of the mixture through the burner under less steam or airpressure; and third, to provide a tip of a shape to cause thoroughcombustion, to be self cleaning, and to direct the flame to the bestadvantage.

To these ends, my invention consists in the novel oil-burner, which Ishall now fully describe by reference to the accompanying drawings, inwhich Figure 1 is a side view, partly in section, of my oil-burner. Fig.2 is a front View of the discharge tip. Fig. 3 is a view of the end ofthe steam or air pipe. Fig. 4: is a side elevation of inner pipe,showing the arrangement, shape and position of the holes.

1 is a head-coupling, to which is fitted the connection 2 for the oiland the connection 3 for the steam or air. Into the end of thehead-coupling l is screwed the body pipe 4 of the burner and into theother end of this pipe is screwed a coupling 5, to which is fitted thetip 6, having a top plug 7. In the face of the tip 6 is made thedischarge or burner-slot 8, which, as seen, has a straight upper wall,and a lower wall, inclined relatively to the upper wall, the spacebetween the walls being unobstructed, as clearly shown in Fig. 2.

Screwed into the steam or air connection 3 is the pipe 9, which extendsinto the body pipe 4, and has its extremity provided with cross slot 10.This pipe 9 has, throughout its length, a number of holes 11, which havethree peculiarities; namely, the series of holes are arranged in anapproximately helical course around the pipe; each hole is made throughthe pipe wall on a slant, open- Specification'of Letters Patent.

ing outwardly with a forward slope, and each hole is laterally andforwardly inclined relative to the longitudinal axis of the pipe. Thesefeatures result in discharging the steam or air into the body pipe fromall around the steam or air pipe, in a forward direction, and in ageneral helical course, thereby creating a forward whirling action ofthe mixture of oil and air or steam, and resulting in a thorough andperfect commingling of the elements of the mixture to bedelivered to thetip; which mixture is further augmented and carried forward by the steamor air issuing from the slitted extremity. of the inner pipe. Thewhirling mixture thus delivered to the tip, gives perfect atomizing ofthe oil; reduces the necessary steam or air pressure; results incomplete and thorough combustion; assists, in connection with theflaring shape of the discharge slot 8 in keeping the latter clean andclear, reduces the smoke and soot to a minimum; and the flame itself, onaccount of the downwardly sloping wall of the discharge slot is directedin such manner as not to burn out boilers, if used under them.

Having thus described my invention, what I claim as new and desire tosecure by Let'- ters Patent is 1. A11 oil-burner comprising an outerpipe, an inner pipe spaced from the outer pipe and terminating short ofthe discharge end of the outer pipe, said inner pipe having an openingin its extremity and provided at intervals in its length with holeslaterally and forwardly inclined relatively to the longitudinal axis ofthe pipe, an oil supply connection to the outer pipe, a steam or airconnection to the inner pipe, and a discharge tip fitted to the end ofthe outer 1 e. p An oil-burner comprising an outer pipe, an inner pipespaced from the outer pipe and terminating short of the discharge end ofthe outer pipe, said inner pipe having an opening in its extremity andprovided at intervals in its length with holes laterally and forwardlyinclined relatively to the longitudinal axis of the pipe, an oil-supplyconnection to the outer pipe, a steam or air connection to the innerpipe, and a discharge tip fitted to the end of the outer pipe, thedischarge tip having a slot with a straight upper wall and a lower wallinclined relathe walls being unobstructed.

3. An oil-burner comprising an outer and inner pipe, said inner pipehaving an opening in its extremity, and provided, at intervals in itslength, withholes laterally and forwardly inclined relative to thelongitudinal axis of the pipe; an oil-supply connection to the outerpipe; a steam or air connection to the inner pipe; and a discharge tipfitted to the end of the outer pipe, said tip having a burner slot witha straight upper wall and a lower wall inclined relative to the upperwall.

4. An oil burner comprising an outer and an inner pipe, the inner pipehaving a slitted forward terminal, and a plurality of holes each spacedfrom one another longitudinally of the inner pipe and disposed toprovide a helical course about the same and each of said holes slopinglaterally and forwardly, and a discharge tip fitted to the outer pipe.

In testimony whereof I have signed my name to this specification in thepresence of tWo subscribing witnesses.
